Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a soil remediation experimental detection device and a detection method thereof. Background Art

[0002] With the acceleration of industrialization and urbanization, the problem of heavy metal contamination of soil is becoming increasingly serious. Heavy metals such as lead, cadmium, mercury, and chromium are difficult to degrade in the soil, which not only leads to a decline in soil fertility and affects the growth of crops, but also enters the human body through the food chain, endangering human health. At present, common soil heavy metal remediation technologies include physical remediation, chemical remediation, and biological remediation. Physical remediation such as the imported soil method is costly and labor-intensive; chemical remediation is prone to secondary pollution; traditional biological remediation has a long cycle and low efficiency. Electrokinetic remediation technology uses the action of an electric field to drive the migration of heavy metal ions, but when used alone, it has problems such as high energy consumption and limited remediation effect; microbial remediation technology uses the adsorption and transformation of heavy metals by microorganisms for remediation, but the remediation speed is slow. Therefore, it is of great significance to develop an efficient and environmentally friendly heavy metal contaminated soil remediation technology and equipment.

[0003] Currently, monitoring and testing are key to ensuring the effectiveness of soil remediation experiments. However, existing soil remediation experimental equipment and testing methods have limitations in terms of real-time monitoring of gas changes, monitoring of microbial populations, and precise control of the mixing process. Traditional monitoring methods often rely on direct sampling and analysis of the soil itself. This method cannot track gas changes in real time during the remediation process, nor can it effectively determine the degree of mixing between the remediation agent and the soil. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a soil remediation experimental detection device and detection method, which solves the problem that traditional methods mainly rely on sampling and analysis of the soil itself, fail to track the changes in gas composition during the soil remediation process in real time, and cannot accurately determine whether the remediation process is fully mixed or whether there is any release of harmful gases.

[0031] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Please see the attached Figure 1 -Attached Figure 4 and Figure 6 The embodiment of the present invention provides a soil remediation experimental detection device, including a mounting plate 1, a transfer sleeve 2 is fixedly connected to the inner wall of the mounting plate 1, a filter element 8 is arranged inside the transfer sleeve 2, a connecting sleeve 3 is detachably mounted on the lower side of the transfer sleeve 2, a switching cavity 4 is arranged on the lower side of the connecting sleeve 3, a first blocking surface 5 is slidingly arranged inside the switching cavity 4, a connecting rod 6 is arranged on one side of the first blocking surface 5, a second blocking surface 7 is fixedly arranged on the other side of the connecting rod 6, and the outer wall of the second blocking surface 7 is slidingly arranged on the inner wall of the switching cavity 4, the mounting plate An overflow pipe 9 is provided on one side of 1, and a through hole is provided inside the overflow pipe 9 and extends to the interior of the transfer sleeve 2. A connecting pipe 12 is provided at the upper opening of the transfer sleeve 2, and a collecting box 10 is provided at the opening on the other side of the through hole of the overflow pipe 9. A gas collection box 13 is provided on one side of the switching cavity 4, and a liquid treatment box 14 is provided on the other side of the switching cavity 4. The lower surfaces of the liquid treatment box 14 and the gas collection box 13 are fixedly connected with an outer shell 11, a screening component is provided in the middle of the outer shell 11, and a reaction component is provided on the upper side of the outer shell 11.

[0033] Specifically, the filter element 8 is first installed inside the transfer sleeve 2, and then installed inside the shell 11 through the mounting plate 1 by means of bolts or the like, and docked with the lower side of the connecting pipe 12. Then, during use, according to the experimental requirements, the gas collection box 13 or the liquid treatment box 14 is opened to push the first blocking surface 5 or the second blocking surface 7 through the gas or liquid to drive the connecting rod 6 to drive the other side to move, thereby blocking the pipeline on the other side. This avoids cross contamination during use and improves the diversity of experiments. When it is necessary to extract gas for experiments during use, the gas collection box 13 is first started to drive the second blocking surface 7 to push the first blocking surface 5 to the other side, and then the air pressure is reduced to half of the pushing pressure, and then the gas inside the reaction tank 21 is extracted. During use, the second blocking surface 7 is connected through the pipeline. The first blocking surface 5 will not move due to pressure, and the filter element 8 will intercept the particles when extracting gas during use. When the filter element 8 needs to be cleaned, the ball valve 24 is closed and the liquid treatment box 14 is started to drive the first blocking surface 5 to move to the other side and flush it with water. Because the upper pressure sewage can only flow to the collection box 10 through the overflow pipe 9, the experimental mode can be quickly switched according to different usage conditions during use. After adding biological or chemical remediation liquid to the interior of the liquid treatment box 14, the liquid is transported to the interior of the reaction tank 21 through the liquid treatment box 14 and the connecting pipe 12 to mix with the soil. During use, a rapid mixing experiment can be performed according to different remediation substrates, and gas experimental samples can be extracted by extracting gas during the experiment, so as to judge the effect of the remediation environment and the remediation results according to gas samples in different time periods.

[0034] Please see the attached Figure 1 and attached Figure 7 The screening assembly includes a first motor 15, the outer wall of which is fixedly connected to the outer wall of the housing 11. A reciprocating rod 16 is fixedly mounted on the output end of the first motor 15, and a mounting claw 17 is rotatably connected to one end of the reciprocating rod 16. A screen 19 is removably mounted on the lower surface of the mounting claw 17, and a slide rail 18 is fixedly connected to the output end of the mounting claw 17. The outer wall of the slide rail 18 is slidably connected to the inner side of the housing 11. A vertical plate 20 is provided on the lower side of the slide rail 18, and the outer wall of the vertical plate 20 is slidably connected to the middle portion of the housing 11.

[0035] Specifically, first, by starting the first motor 15 to drive the reciprocating rod 16, the mounting claw 17 moves back and forth along the slide rail 18 inside the shell 11, driving the screen 19 to perform a screening operation. Through this screening, soil particles of different fineness can be separated during use, so as to facilitate subsequent soil remediation sample sampling and testing. During the screening process, the dust and fine particles raised will be captured in time to avoid polluting the experimental environment and affecting the experimental results. The vertical plate 20 slides with the inner wall of the shell 11, further ensuring the stability of the screening component and avoiding offset or unevenness during the screening process. During the screening operation, the gas collection box 13 and the liquid treatment box 14 can be used in conjunction to effectively control the extraction and filtration of the gas, ensuring that the soil sample is not affected by the external environment. The screened soil sample is collected by the collection box 10 below for centralized processing, providing reliable remediation effect data. During use, the screening process of the soil remediation experiment is made more accurate and efficient, while also effectively reducing the pollution of the experimental environment and optimizing the effect of soil remediation.

[0036] Please see the attached Figure 1 , Attachment Figure 8 and attached Figure 9 The reaction assembly includes a vertical plate 20, the lower surface of which is fixedly connected to the upper surface of the housing 11. A second motor 22 is fixedly connected to one side of the vertical plate 20, and a mounting bracket 23 is fixedly connected to the output end of the second motor 22. A reaction tank 21 is detachably mounted on the inner wall of the mounting bracket 23. A ball valve 24 is provided in the middle of the connecting pipe 12, and an opening on one side of the connecting pipe 12 is provided inside the reaction tank 21. A sealing cover 25 is provided at the top of the reaction tank 21, and a protective shell 26 is fixedly connected to the upper surface of the sealing cover 25. A third motor 27 is fixedly connected to the inner top wall of the protective shell 26. A worm 28 is connected to the output end of the third motor 27, and a worm wheel 29 is meshed with the tooth end of the worm 28. A centrifugal rod 30 is fixedly connected to the outer wall of one side of the worm wheel 29.

[0037] Specifically, first, the soil that needs to be repaired or tested is added to the interior of the reaction tank 21 by opening the vertical plate 20, and then the vertical plate 20 is reset. During use, the mounting frame 23 is driven to rotate by the second motor 22, thereby driving the reaction tank 21 to rotate during use. During use, the soil deposited on the bottom can be turned over, and at the same time, the worm gear 29 and the adjustment bracket 31 are driven by the reaction tank 21 and the worm 28 to control the mixing column 34 to rotate when it moves up and down, which further increases the uniformity of soil mixing during use. During use, the biological repair liquid or chemical repair liquid can be quickly mixed with the soil, further increasing the experimental speed and reducing the experimental cycle.

[0038] Please see the attached Figure 9The inner wall of the centrifugal rod 30 is rotatably connected to an adjustment bracket 31. The outer wall of the adjustment bracket 31 is fixedly connected to an adjustment claw 32. The outer wall of the adjustment claw 32 is provided with an adjustment rod 33. The inner part of the adjustment rod 33 is slidably mounted on the lower outer wall of the worm 28. The outer wall of the adjustment rod 33 is fixedly connected to a mixing column 34. The lower end of the worm 28 is configured as a square. The inner part of the adjustment rod 33 matches and slides with the end of the worm 28. The bottom end of the adjustment rod 33 is fixedly connected to a side column 35. The outer wall of the side column 35 is slidably connected to the outer wall of the reaction tank 21.

[0039] Specifically, the centrifugal rod 30 drives the adjustment bracket 31 during the driving process, and the worm gear 29 drives the centrifugal rod 30 to perform centrifugal motion during the rotation process, thereby driving the adjustment bracket 31 to move up and down. During the movement, the square shape of the lower end of the worm 28 drives the adjustment rod 33 to rotate, and drives the adjustment rod 33 to move up and down during the rotation through the up and down motion. The adjustment rod 33 synchronously drives the side column 35 to rotate, so that the soil on both sides can be stirred. At the same time, the side column 35 also has the effect of cleaning the inner wall of the reaction tank 21. During use, the side soil can be further prevented from being unable to be mixed, and the soil mixing effect can be further increased during use.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
